Overview
The Vishay 1N4937-E3/53 is a fast switching plastic rectifier featuring a single silicon junction in a DO-41 (DO-204AL) molded epoxy package. It supports a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 1.0 A at 75 °C ambient temperature. The device exhibits a maximum instantaneous forward voltage of 1.2 V, a maximum DC reverse current of 5.0 μA at rated blocking voltage, and a typical reverse recovery time of 200 ns. It withstands a peak forward surge current of 30 A and operates within a junction temperature range of -50 to +150 °C.
Feature Summary
- Fast switching capability designed for high efficiency applications
- Low leakage current characteristics under rated DC blocking voltage
- High forward surge current handling capability
- Molded epoxy body with UL 94 V-0 flammability rating
Applications
- Fast switching rectification in power supplies
- Inverter circuits
- Converter topologies
- Freewheeling diodes for consumer electronics
- Telecommunication equipment
Procurement Notes
Verify the specific suffix designation against official Vishay documentation to confirm packaging configuration and compliance status. Confirm that the ordering code matches the required delivery mode and base quantity specifications provided in the manufacturer's ordering information section.
Selection Notes
Select this component for designs requiring fast recovery times and low forward voltage drop in through-hole applications. Ensure the circuit operating conditions remain within the specified thermal limits and do not exceed the maximum repetitive peak reverse voltage or average forward current ratings defined in the datasheet.
Part Context
This part belongs to the 1N493x series of fast switching plastic rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings ranging from 50 V to 600 V, all sharing identical mechanical dimensions and electrical performance characteristics except for the blocking voltage specification.
Replacement Considerations
Cross-reference with other manufacturers offering DO-41 packaged fast recovery rectifiers with equivalent 600 V reverse voltage and 1 A forward current ratings. Verify compatibility regarding reverse recovery time and forward voltage drop before substitution.
